Description

Gemcitabine (G) Plus (+) Erlotinib (E): Rash ≥ Grade 2

Participants began a 4 week run-in period where they received gemcitabine, 1000 milligrams per square meter (mg/m^2), intravenously (IV), on Days 1, 8, 15, 22 until development of a rash Grade ≥ 2. Participants also received erlotinib, 100 milligrams (mg), orally (PO) as a film-coated tablet, once daily until development of a rash Grade ≥ 2. Participants were not randomized to a treatment arm, but continued to receive the standard treatment of gemcitabine, 1000 mg/m^2, IV, on Days 1, 8, and 15 of consecutive 4 week cycles, and erlotinib, 100 mg, PO as a film-coated tablet, once daily until disease progression, unacceptable toxicity, or withdrawal for up to 46 months.

G+E Standard Dose: Rash Grade Less Than (<) 2

Participants completed a 4 week run-in period where they received gemcitabine, 1000 mg/m^2, IV, on Days 1, 8, 15, 22. Participants also received erlotinib, 100 mg, PO as a film-coated tablet, once daily for 4 weeks. Participants without evidence of clinical progression and who had not developed rash Grade ≥ 2 or any other toxicity leading to dose adjustments or discontinuation were randomized to receive gemcitabine, 1000 mg/m^2, IV, on Days 1, 8, and 15 of consecutive 4 week cycles and erlotinib, 100 mg, PO as a film-coated tablet, once daily until disease progression or unacceptable toxicity, or withdrawal for up to 46 months.

G+E Escalating Dose: Rash Grade < 2

Participants completed a 4 week run-in period where they received gemcitabine, 1000 mg/m^2, IV, on Days 1, 8, 15, 22. Participants also received erlotinib, 100 mg, PO as a film-coated tablet, once daily for 4 weeks. Participants without evidence of clinical progression and who had not developed rash Grade ≥ 2 or any other toxicity leading to dose adjustments or discontinuation were randomized to receive erlotinib, beginning at 150 milligrams per day (mg/day), PO as a film-coated tablet, once daily and increasing in increments of 50 mg every 2 weeks up to a maximum of 250 mg/day, until development of a Grade ≥ 2 rash, or occurrence of other, non-rash, dose-limiting toxicity; treatment was continued until disease progression, unacceptable toxicity, death or withdrawal for up to 46 months. Those participants also received gemcitabine, 1000 mg/m^2, IV, on Days 1, 8, and 15 of consecutive 4 week cycles until disease progression, unacceptable toxicity, or withdrawal for up to 46 months.

G+E: No Rash Non-Eligibl

Participants began a 4 week run-in period where they received gemcitabine, 1000 mg/m^2, IV, on Days 1, 8, 15, 22 until the appearance of evidence of clinical progression or other toxicity leading to dose adjustments or discontinuation. Participants also received erlotinib, 100 mg, PO as a film-coated tablet, once daily until the appearance of evidence of clinical progression or other toxicity leading to dose adjustments or discontinuation. Participants were not randomized to a treatment arm, but continued to receive the standard treatment of gemcitabine, 1000 mg/m^2, IV, on Days 1, 8, and 15 of consecutive 4 week cycles, and erlotinib, 100 mg, PO as a film-coated tablet, once daily until disease progression, unacceptable toxicity, or withdrawal for up to 46 months.

G+E: Early Drop Out

Participants began a 4 week run-in period where they received gemcitabine, 1000 mg/m^2, IV, on Days 1, 8, 15, 22 for up to 4 weeks. Participants also received erlotinib, 100 mg, PO as a film-coated tablet, once daily for up to 4 weeks.

Explanation of how the number of participants for analysis was determined.
Includes whether analysis was per protocol, intention to treat, or another method.
Also provides relevant details such as imputation technique, as appropriate.

Safety analysis population (SAP): all participants who received at least 1 dose of the trial medication and had at least 1 safety follow-up, whether withdrawn prematurely or not.
